Kim Kardashian -- Moving Houses After Trespasser Scare

Kim Kardashian was so freaked after a strange man rang the doorbell at her Beverly Hills home last weekend -- she has decided to dump the property entirely ... and find a new house ... in a gated community.

Sources tell TMZ, Kim's currently house shopping in several exclusive gated communities in the L.A. area -- including Bel Air ... and Mulholland Estates, where both Charlie Sheen and Paris Hilton own houses.

She hasn't made up her mind yet -- but we're told Kim now refuses to live in any house that doesn't have round-the-clock gated security.

TMZ broke the story -- cops were called to Kim's home late Saturday night, when a man showed up on her property with a bunch of luggage and rang the doorbell ... insisting Kim invited him to stay with her.
